The Copper Mining Process. Once it's located within the earth, copper ore goes through eight stages before the consumer sees it in various products that affect every day life in the home and business. These eight stages include: Mining; Grinding; Concentrating; Roasting; Smelting; Conversion; Anode.Copper extraction - WikipediaCopper extraction refers to the methods used to obtaining copper from its ores. The conversion of copper consists of a series of chemical, physical, and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining.
